In the letter, he said for days, because he was under suicide watch, he was forced to sleep naked and without a blanket.

The Guardian reports that during his earlier confinement in Kuwait, Manning testified that he lost control:

"Coombs asked Manning whether he had any recollection of an incident on 30 June 2010, when he had lost control of himself to the extent that doctors had to intervene. 'He was screaming, babbling, banging his head against the cell,' said Coombs.

"Manning replied: 'I knew I had just fallen apart, everything is foggy and hazy at that point.'"

As we reported, Manning offered to plead guilty to minor charges in the case, but not to accusations that he was spying and aiding American enemies.

The judge in the case approved those guilty pleas, today, but the U.S. government has not said whether it will move forward with the more serious charges.

The AP explains further:

"The military contends the treatment was proper, given Manning's classification then as a maximum-security detainee who posed a risk of injury to himself or others.

"Col. Denise Lind's ruling doesn't mean the pleas have been formally accepted. That could happen in December.

"But Lind approved the language of the offenses to which Manning would admit.

"She said those offenses carry a total maximum prison term of 16 years."

Update at 11:12 p.m. ET. Julian Assange Weighs In:

WikiLeaks founder Julian Assange, in an article for The Huffington Post, writes that today also marks the second anniversary of the release of tens of thousands of diplomatic cables, for which Manning is an alleged source. Assange writes:

"The material that Bradley Manning is alleged to have leaked has highlighted astonishing examples of U.S. subversion of the democratic process around the world, systematic evasion of accountability for atrocities and killings, and many other abuses."
